• There’s a different format to the monthly Jazz & Jam at Foyles, Charing Cross Road, on Sunday morning (March 19). Instead of the usual house band, 60 young musicians in three National Youth Jazz Orchestra Academy ensembles are playing an initial set of big band classics and new material. This is being followed by a bumper jazz jam in the afternoon open any young musician under 18. Should be absolutely terrific fun for beginners and more experienced players.
